Free Traffic Legal Advice

If you look at the aerial photo there are cars parked on the bridge like you were so that could support that you weren't aware it had changed.

Having looked at streetview the only thing I could think of is that it is the approach to traffic lights, but I have always thought, and could be wrong, that it is only zig zags that would enforce an approach to lights, and common sense would kick in that you wouldn't park near a crossing/lights, but the distance here would almost certainly not be relevant here.

I'd say the officer has got it wrong, although on 2 different years on streetview there are suspension notices on the fence, but as above going to court to prove your point could end up becoming quite costly if the court find against you, and then end up with a larger fine and costs.
It may be one to speak with the local councillor about otherwise take the £30 on the chin.

Do you or anyone who was with you at the cinema have Google maps tracking your journeys on the timeline? If so that would help to show if you were in that area or what time you got home which could assist in showing that you weren't in the area if there are ANPR cameras on your route home that would corroborate this.

Just be careful in case Chief Inspector Corner of the Yard is on here monitoring this forum and reporting back.

Depending on if they were actually wanting to stop you in the first place you'd be looking at failing to stop, and potentially careless/dangerous driving offences. They'd then be looking at the actual car itself - VED, insurance, MOT etc, and you could expect a knock at the door with them wanting to have a look around to see what you may have been trying to hide by running off from them before any other potential charges may be looked at.

The only way to know what will happen next is to go and speak with them as said above.

I've found this public notice online.

I discovered when my wife renewed hers for the first time that they don't renew from the anniversary date, but from the date they process the renewal, so in other words if your licence expired on 1st July and you sent it off today the next expiry date could be 9th May depending on if they processed it as soon as it is received. Needless to say when it was time for mine to be renewed I sent it in a few days before and only lost 2 days. I'd have left it later but I've got a volunteer role where my licence is on auto check and if I let it expire I lose the driving entitlement, even though I rarely drive for them.

So if you renewed as soon as you had the letter over the course of your lifetime you could end up losing almost a year from early renewals.
